[英]Equivalent of u_int16_t from windows stdint.h in gnu?
到目前为止,我假设u_int16_t
是一个名为stdint.h的MSVS头文件内部的Windows类型。 我正在使用GNU g ++作为编译器(实际上是带有mingw的代码块),我想知道typedef unsigned short uint_least16_t;
(在mingw的stdint.h内部)是等效的还是可以做些什么来包括这种类型?
这个问题实际上与编译用于MSVS的google sparsehash项目文件有关,但是我正在使用代码块。 这就是它给我的错误(顺便说一句,该错误重复了很多次)。

如果没有任何定义u_int16_t
标头。 自己做 :
#include <stdint.h>
#include <stddef.h>
typedef uint16_t u_int16_t;
typedef size_t size_type;
我不确定如何指定u_int16_t
; 如您所知,这是非标准的。 您应该使用什么取决于您想要的:
uint16_t // Exactly 16 bits, only present if the hardware
// has such a type.
uint_least16_t // The smallest type which has at least 16 bits.
uint_fast16_t // The fastest type which has at least 16 bits.
在大多数现代机器上,这三个机器都是相同类型的typedef,通常是unsigned short
,我经常在“便携式”代码中使用uint16_t
,因为这是最容易编写的程序,也是我遇到机器的机会。定义非常非常苗条。 (唯一不被定义的现代机器是Unisys大型机和某些具有32位字节的嵌入式处理器。)
关于size_type
,这可能是 size_t
。 在<stddef.h>
或<cstddef>
(它是std::size_t
)中,而不是在<stdint.h>
。
您应该运行./configure
脚本。 不幸的是,这在Windows上可能是一个真正的痛苦,因此项目的src/windows
目录中具有./configure
为VC ++生成的标头。 这就是u_int16_t
适用于VC ++的原因-它不在任何VC ++头文件中,但是config.h
和sparseconfig.h
文件会处理它。
不幸的是,VC ++配置不适用于MinGW。 理想情况下,您将能够为MinGW运行./configure
,但是正如我提到的那样,在Windows上可能很难。 这是一个config.h
文件,它使我能够编译项目的simple_test.cc
程序。 需要对spareseconfig.h
进行相应的更改。 此外,对于较大的项目使用范围,或者如果您使用不同版本的MinGW(例如,MinGW 4.7+应该使用<unordered_map>
而不是<ext/hash_map>
),可能需要进行不同的调整:
